Abstract

Salvinia molesta is an aquatic weed having very high growth rate. The high abundance of this species biomass could be utilized as a source of alternative energy. This research was aimed to utilize S. molesta as a substrate for biogas production using batch system in order to reduce euthrofication effect in a lake. Cow manure was used as starter for anaerobic process because containing bacteria. Proximate test was conducted to analyze the chemical characteristics of the aquatic weed. Chemical oxygen demand, total solid, and total volatile suspended solid of weed and manure were analyzed according to the APHA 2012 method. Biogas composition was analyzed with gas chromatography. The results showed that the S. molesta contained high lignin content and low C:N ratio. Hydrolisis and acidification process occured very rapid, resulting in an increase of the weed and manure mixture COD. In the other hand, the decreased of COD removal was caused by the massal death of methanogenesis bacteria. The total solid and total volatile suspended solid content were not significantly decreased. Potential biogas production from S. molesta was 58.16 L.kg-1 with 318.29 mL.gram VS-1day-1 of methane production. This production value was still low or compared to that of cow manure which have been established as biogass materials and need modification to improve the biogas production.

Abstract

Bioplastik adalah plastik yang dapat didegradasi oleh mikroba yang ada di dalam tanah karena adanya kandungan pati di dalamnya. Bioplastik diharapkan merupakan salah satu solusi dari masalah lingkungan yang disebabkan oleh penumpukan sampah kantong plastik belanja yang menjadi beban lingkungan. Secara komersial sudah ada bioplastik yang diproduksi dengan variasi jumlah penambahan pati singkong atau pati jagung, namun kendalanya adalah harga produk masih mahal jika dibandingkan dengan harga kantong plastik konvensional pada umumnya, karena tepung dan pati tersebut masih dibutuhkan di sektor pangan dan energi. Pada penelitian ini bioplastik dibuat dengan menggunakan pati yang diekstraksi dari biji durian yang selama ini merupakan limbah, untuk dicampur dengan biji plastik LDPE pada variasi konsentrasi pati 0% sampai 50%. Sebagai pembanding dipakai pati dari empulur sagu, sehingga karakteristik fisik seperti warna dan sifat mekanik dari bioplastik seperti kekuatan tarik, perpanjangan putus, dan kekerasan dapat dibandingkan. Uji penurunan berat bioplastik dilakukan dengan pemendaman di dalam tanah selama 8 minggu. Hasil uji Anova menunjukkan perlakuan jenis pati dan konsentrasi pati yang ditambahkan tidak beda nyata (p>0,05) terhadap kehilangan berat plastik. Analisis SEM dilakukan untuk membandingkan rongga diantara molekul pati dengan polimer plastik pada perbesaran 2500x yang menyebabkan kekuatan mekanik plastik menjadi berkurang dan rapuh ketika ditarik. Pati biji durian 10% terbukti optimal dapat digunakan sebagai substitusi polimer tanpa penambahan aditif dalam pembuatan bioplastik, dengan karakteristik mekanik yang dapat dibandingkan dengan pati sagu dan pati singkong, namun memiliki laju degradasi yang lebih rendah.

Abstract

ABSTRACTMangrove ecosystem in some regions of the Bintan Bay has suffered damage due to development of human settlements, developing of land transport infrastructure, and also logging by the community. The aim of this study was to assess the level of damage, factors affecting the damage, and to calculate the estimated value of claims for damaged mangrove ecosystem in the Bintan Bay, Bintan District. The results showed that mangrove vegetation in Bintan Bay consists of 16 species. Based on the analysis of standard criteria and guidelines for mangrove destruction KEPMENLH 201, 2004, the quality of mangroves in Bintan Bay was considered in a good criteria (very dense and medium) and damaged criteria (rare). The observation of satellite images from 1990 to 2013 showed that mangrove area decreased by 501.39 hectares or 27.1%. Contributing factor due to the decrease of mangrove trees was to fuel the manufacture of charcoal, construction of infrastructures such as roads, ports of fishing boats and also the establishment of the fish pond. Based on rehabilitation application scenario for 15 years, the total area of compensated mangrove due to its damage was 1091.727 hectares with rehabilitation cost of about Rp 30.372.391.000,00. Meanwhile, for 30 years scenario rehabilitation, the total damage mangrove area that should be compensated was 1743.406 hectares.  Keywords : Bintan Bay, mangrove ecosystem, estimated value damage claims
